anyone know the Savage Mark I G?

I've always liked single shot rifles grooved for scope and with swivel studs...... rare configuration.

This little rifle has caught my eye but man there is very little info out there. Will it chamber shorts and longs? Savage website only mentions LR but I'd be shocked if it wouldn't accept the shorter .22 cartridges. And what does "walnut finished hardwood" mean? How long has it been in production?

Quality? I'd love any info from owners or shooters who've shot this thing.

Thanks

Anyone have suggestions other than the Mark I G? I'm open to used stuff too
